To Clean or not to clean?

These are some open specimens I found at Mazonia Lakes.  I think the set may be a crayfish.  The other two seem to be some type of plant.  I didn't know if I should soak these in vinegar.  I am afraid if I do I may not be able to see the detail.

The first plant looks like a Neuropteris pinnule, and the second looks like Cyclopteris, to me. 

I can't make anything out on your first item.  

Maybe some of the Mazon hunters will have a look.

It appears to be a Neuropteris carrii Lesquereux 1884. The picture here is of one of Lesquereux's  syntypes for this species. And it compares very well to what you have. Here is a brief description; The venation is heavy, well marked, very distant, nearly erect and parallel near the base. The lateral veins gradually curve and become flexuous and may be reticulated. They meet the margin very close and at nearly a right angle to the margin. The venation is reticulated, which means in this species the lateral veins occasionally bump together but do not merge. This is hard to see and may be the case where only a few veins near the margin are found in that state. I can not see any from your picture, but this is likely do to the state of preservation. It is even hard to find in this picture of the type specimen, which is often the case.

 

Hope this helps,

Jack

Thanks for your input.  I tried to outline the area I think could be a crayfish (or something).  I just discovered the paint button on my computer   It is hard to see in the picture but it is 3D in actuality.  I haven't figured out how to capture the depth in a picture.
